• Each network in a Novell internet, including all LANs and
WAN links, must be assigned a network number. Novell file
servers also have an internal network number. These
network numbers must be unique across the Novell
internet—no two networks or file servers may use the
same network number. All devices attached to a network
must use the same network number to refer to the
network. Check to see what numbers your file servers are
using. Many schemes exist to ensure that numbers are kept
unique, for example, using the hexadecimal representation
of the IP address or the telephone number of each location.
• All routers, file servers and workstations attached to an
Ethernet LAN must use the same Ethernet encapsulation or
frame type. The following table lists the Novell frame type
and the equivalent AR router encapsulation:
Novell Frame Type
Ethernet_802.3
Ethernet_802.2
Ethernet_II
Ethernet_SNAP
You can determine the file server name, internal network
number, Ethernet frame type and Ethernet network number
used by a Novell file server, by interrogating the file server
itself. From the management console attached to the Novell file
server, at the system console prompt type the command
"config" and record the values of the fields "File server name",
"IPX internal network number", "Frame type" and "LAN
protocol". You can also access the system console by running
the rconsole utility from any workstation logged in as
supervisor. For more details, contact your local Novell network
administrator or refer to the Novell documentation.

CONFIGURING IPX

The following steps are required:
1. Configure the PPP link.
2. Configure the routers for IPX.
3. Test the configuration.
Configure the PPP Link
Configure PPP interface 0 on each router to use the wide area
link. See Getting Connected for information about configuring
PPP to use a synchronous link. See Configuring ISDN for
information about configuring PPP to use an ISDN call. If the
Router Encapsulation
802.3
802.2
EthII
SNAP
PPP interface is configured for dial on demand operation (see
Configuring ISDN Dial on Demand) or bandwidth on demand
operation (see Configuring ISDN Bandwidth on Demand), these
services will automatically be used by the IPX routing software.
Configure IPX Routing
1 Purge the IPX static database to clear any preexisting IPX
configuration and enable the IPX routing software on each
router, using the commands:
PURGE IPX
ENABLE IPX
2 On the Head Office router define two IPX circuits, one for
the Ethernet interface and one for the wide area link, using:
ADD IPX CIRC=1 INT=ETH0 NETW=401
ENCAP=802.3
ADD IPX CIRC=2 INT=PPP0 NETW=129
3 Repeat this procedure on the Remote Office router,
defining one IPX circuit for the Ethernet interface and one for
the wide area link, using:
ADD IPX CIRC=1 INT=ETH0 NETW=12
ENCAP=802.3
ADD IPX CIRC=2 INT=PPP0 NETW=129
4 The routers are now configured for IPX and can exchange
routes and service information.
Test the Configuration
1 Examine the route table and service table on each router,
using the commands:
SHOW IPX ROUTE
SHOW IPX SERVICE
The route table will contain paths from each Novell device
which advertises routes, for example file servers and routers.
The service table lists all the services, such as file services and
print services, that devices are advertising.
Note: The actual contents of the table varies with the number and
type of file servers present on the network, but there should be a
route from each router to the other, and all services shown as local
(i.e. via eth0) on one router, should also be visible on the other router,
via the PPP link.
2 Test that a workstation on the Remote Office LAN can
login to the file server on the Head Office LAN.
